What you forget is that they have to attempt access to your site to get banned (redirected 301) so thats why Pauls mod is showing those to you, also bots don't access homepage then select a forum then select a thread, they just go straight for a thread (or post), so as soon as that happens Pauls mod will log them, but if you look at WOL are they there now?
I doubt it

, Pauls mod is doing the job it's set out to, mine should be doing the job too, did you test that UA i gave above at the link i gave? If so what were the results?
